Yes csm is enabled. When I turn off mining mode it is enabled.

What do you mean by installation media type? Like the USB drive I used to install windows has to be formatted a certain way? Or are you referring to the BIOS option "Storage Boot Option Control"? I have that setting on legacy. Should I change it to UEFI?

you should install Windows 10 on a GPT partition and boot your Windows installation using UEFI bootloader, yes. CSM should be disabled. otherwise you'll have many kinds of strange issues while trying to make your 6+ GPUs rig work.

if you've installed Windows using MBR partition scheme, you can convert it to GPT using MBR2GPT tool.
